Deuteronomy 3:16
“To the Reubenites and to the Gadites I gave from Gilead even to the valley of the Arnon, the middle of the valley, and its border, even to the river Jabbok, which is the border of the children of Ammon;”
What does Deuteronomy 3:16 mean?
Moses is describing the land east of the Jordan River that he's giving to two of Israel's tribes, Reuben and Gad, as their permanent home. He's being specific about the boundaries—using natural landmarks like rivers and valleys—so there's no confusion about where one tribe's territory ends and another begins. This mattered deeply because land meant security, livelihood, and a place to belong for each family and tribe. The careful detail here reflects how seriously Moses took the responsibility of fairly dividing what God had promised to give them.
